The coefficient of restitution (COR) is a measure of the restitution of a collision between two objects: how much of the kinetic energy remains for the objects to rebound from one another vs. how much is lost as heat, or work done deforming the objects. The mathematics were developed by Sir Isaac Newton in 1687.
